All-optical routers that can manipulate packets of light, pulling some signals off a fiber and sending the rest on their way, may not be widely available for years.
So unless we want to stop technological progress, pinch off our fiber pipes to the world and to each other, and freeze capital, I think the only long-term remedy is education.
There, a piece of hardware called the concentrator unit plucks the data off a fiber-optic network, reformulates it into a signal at 2 to 30 megahertz and injects that signal onto the power line.
